I went to ¼­´ë¹® museum of natural history. There are lots of imformations about Earth, Dinosaurs, and evolution. I was surprised at Earth's birth. Earth formed about 4.6 billion years ago. First the Earth was very hot because of magma. So steem goes to sky and it makes up the cloud. So the rain droped and Earth cooled. Next I  was surprised at evolution. First creature is very simple. But later, it complicates more than before. Isn't it interesting? And lastly I was surprised at  dinosaurs. I knew there are two types of dinosaurs and how can seperate them. Carnivore dinosaurs eat meat. And they have speacial characters. First they have sharp teeth. Second they usually have two legs and two arms. Then how about herbivore? They have speacial characters too. First they have smooth teeth. Second they have body protection. And third they have four legs.
